DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 10 thereof, a new vehicle jack device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 10, the vehicle lift system 10 generally comprises a vehicle 12 that includes a power supply port 14. A housing 16 has a bottom wall 18, a top wall 20 and a peripheral wall 22 that is attached to and extends between the top 20 and bottom 18 walls. A sleeve 24 is attached to and extends upwardly from the housing 16. A piston 26 is mounted in the sleeve 24. The bottom wall 18 extends outwardly from the peripheral wall 22 to provide additional stability for the housing 16.

A drive assembly 28 is mechanically coupled to the piston 26. The drive assembly 28 is actuated in a first direction to raise an upper end 30 of the piston 26 with respect to the housing 16. The drive assembly 28 is actuated in a second direction to lower the upper end 30 of the piston 26 with respect to the housing 16. The drive assembly 28 is removably coupled to the power supply port 14 to supply electrical power to the drive assembly 28. The drive assembly 28 includes a screw 32 that is threadably coupled to the piston 26. The screw 32 has a bottom end 34 that is positioned within the housing 16. A gear assembly 36 is mechanically coupled to the screw 32. The gear assembly 36 is positioned within the housing 16. A motor 38 is mounted in the housing 16 and a drive shaft 40 is coupled to the motor 38. The motor 38 is actuated to rotate the drive shaft 40 in a first direction or a second direction. The drive shaft 40 is mechanically coupled to the gear assembly 36. A dividing wall 42 divides the motor from the gear assembly 36. A power cord 44 is electrically coupled to the motor 38 and extends through the housing 16. The power cord 44 terminates with a male power port plug 46. An actuator 48 is electrically coupled to the motor 38 and is used to turn the motor 38 on in a first direction or a second direction.

A plurality of engaging members 50 is provided. One of the engaging members 50 is removably attached to the upper end 30 of the piston 26 and engages the vehicle 12. Each of the engaging members 50 includes a connector 52 removably couplable to the upper end 30 and a support 58 abuttable against the vehicle 12 or other object to be lifted. The connector 52 comprises a tube extendable into a slot in the upper end 30. The tube, or connector 52, has a plurality of sets of two aligned apertures 54 therein. The piston 26 has an opening 56 extending therethrough. A locking pin 60 is removably extendable through the opening 56 and an aligned one of the sets of the aligned apertures 54. The support 58 is attached to a top end of the connector 52.

The support 58 of a first engaging member 62 of the plurality of engaging members 50 comprises a panel 64 having a first lateral edge 65 and a second lateral edge 66. The panel 64 has an upper surface 67 that is concavely arcuate from the first lateral edge 65 to the second lateral edge 66. The support 58 of a second engaging member 68 comprises a plate 69 that is planer and has a first edge 71, a second edge 72, a third edge 73 and a fourth edge 74. A U-shaped catch 75 is attached to and extends along a length of the first edge 71. The support 58 of a third engaging member 76 of the plurality of engaging members consists of a panel 78 having a planer upper surface. FIG. 8 shows a third engaging member having both a circular or a rectangular shaped panel 78.

In use, one of the engaging members 50 is selected and coupled to the piston 26. The housing 16 is then placed under the vehicle 12 and the plug plugged into the vehicle 12. The piston 26 is then raised to cause a portion of the vehicle 12 to be lifted. After the vehicle 12 is no longer being worked on, such as for a flat tire, the piston 26 is lowered.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
